It is used in dental department, operating rooms, doctor consultation and wild healing. Characteristic: Adopt high power LED for lighting, long life of about 50000 hours. The integration of power box and light makes it concise, lighter and wireless. There are two biggest characteristics of it: the configuration of power box enables you to change it quickly and conveniently so that normal work gets guaranteed ; Auxiliary power box is of different color to distinguish, note that the main source should recharge in time! Product component: lamp holder, hood, two power boxes, charger etc. Power supply time of the auxiliary one:2H Charge Time: 6H Input voltage: 100V-245V 50HZ-60HZ IV Requirements of working environment A. Environmental temperature: -10℃~+40℃ B. Relative humidity: ≤75% C. The atmosphere: 86.0 kPa~106.0kPa V Product list Head light: one Power box: one Power line: one VI Product interface II. Performance Summarize: This product uses wide voltage power supply system. Lamp holder is composed of optical lens and grating. The joint design of lamp holder and hood can realize the effective regulation of up and down angle. This product is equipped with a magnifying glass joint, can be used together with a magnifying glass. The design and production of this light source strictly executes the first part of the safety requirements of medical electrical equipment GB4793.1-2007: general requirements which is guaranteed in safety.
